I'am not going that way.
As I don't what system or version you are.
So let's assume you are using windows xp pro.
For the first thing. You should not login to your system with administative right on your system.
Use just typical user. Almost all tasks could be done with that account type.
This way, you can safely filter most virus infect you system casue there are not way to save datas
to the important location such as %windir% or %windir%\system32 folder. But just some user profile and its registry.
You may also add yourself to the Power Users Group if you have some application that don't run correctly.
(Just by using the Local Users and Groups MMC Console on the Administrative Folder on the Control Panel)
Use NTFS permissions.
Remove all write and modifiy permissions from all folder that don't need it. Apply this only to folders that really require data change.
Things such as games and the like can easier be changed to read only and just some of it (files) need write/modify permission.
All these will not prevent you from infecting virus from Internet or elsewhere. But it should be able to prevent you from
re-installing the whole OS.

But most Windows users I know will easily be irritated by the restrictions imposed on this kind of account and would rather prefer the admin account at all times. Well it's safety Vs convenience; the debate goes on....
